update lang/sbcl to 1.0.54, and adjust dependent ports (this allows sbcl to
be build WITH_THREADS on recent versions of FreeBSD once again) [1]; rename
*.core files in sbcl and math/maxima so that they are not removed by
disk-cleaning scripts [2]; make it possible to use the makesum target in sbcl
WITH_SBCL; fix maxima build WITH_CMUCL, and place a default memory cap of
1GiB on amd64; reduce default output from a few targets in maxima, and defer
patch cleaning to the pre-build target to make debugging easier

Feature safe: yes

Bump portrevision due to upgrade of devel/gettext.
The affected ports are the ones with gettext as a run-dependency
according to ports/INDEX-7 (5007 of them) and the ones with USE_GETTEXT
in Makefile (29 of them).

Mass-conversion to the USE_AUTOTOOLS New World Order. The code present
in bsd.autotools.mk essentially makes this a no-op given that all the
old variables set a USE_AUTOTOOLS_COMPAT variable, which is parsed in
exactly the same way as USE_AUTOTOOLS itself.
Moreover, USE_AUTOTOOLS has already been extensively tested by the GNOME
team -- all GNOME 2.12.x ports use it.
Preliminary documentation can be found at:
http://people.FreeBSD.org/~ade/autotools.txt
which is in the process of being SGMLized before introduction into the
Porters Handbook.
Light blue touch-paper. Run.

Whoa there, boy, that's a mighty big commit y'all have there...
Begin autotools sanitization sequence by requiring ports to explicitly
specify which version of {libtool,autoconf,automake} they need, erasing
the concept of a "system default".
For ports-in-waiting:
USE_LIBTOOL=YES -> USE_LIBTOOL_VER=13
USE_AUTOCONF=YES -> USE_AUTOCONF_VER=213
USE_AUTOMAKE=YES -> USE_AUTOMAKE_VER=14
Ports attempting to use the old style system after June 1st 2004 will be
sorely disappointed.

Bugfix. fix wish --> wish8.4 to fix xmaxima. Sort out INFO files a
bit better, and allow different lisp compilers to be used. The clisp
compiler dumps core, so mark that case as an error until it can get
fixed. Fix the COMMENT a bit to fit in with sysinstall better.
